ci: register the nine tests main's execution registry does not know about - #13710
Merged

Conversation
…bout scripts/ci/validate_test_execution_registry.py fails on main right now: nine files under tests/ exist with no entry in tests/test-execution.toml, and the "test exists but has no execution registry entry" check is unconditional, so the preflight guard group is red for every pull request regardless of what it touched. Five of the nine arrived with pull requests merged today (#13666, #13673, #13677, #13696, #13701) and four did not. All nine run on a Linux runner, so all nine take the linux-guard lane: ci-guards.yml test_ci_app_host_result_accounting test_ci_workflow_guards_are_wired test_ios_screenshot_capture_guard test_ios_upload_array_expansion test_merge_xcstrings test_release_homebrew_gate test_tui_publish_dispatch_budget testbox-broker-guard test_ci_actionlint_covers_every_workflow ci-artifact-transport test_ci_selective_layer_wiring test_ios_screenshot_capture_guard was the one with no execution path at all: it arrived with the screenshot fail-fast fix in #13675 and no workflow ever ran it. It joins release-ios, beside the other iOS guards. It degrades cleanly where ruby is absent, printing a skip rather than failing, so a Linux lane suits it. The validator required a linux-guard test to appear in ci-guards.yml specifically, which rejects two of these even though they demonstrably execute on every pull request: testbox-broker-guard.yml deliberately carries no path filter, and ci-artifact-transport.yml owns its own. The check now asks whether any workflow runs the test, which is the property the lane is asserting. An entry naming a test that nothing runs is still rejected -- verified by temporarily moving tests/test_vm_scp.py to linux-guard, which fails with "linux-guard lane is not run by any workflow". Entries go into the alphabetically sorted tail of the manifest in position, so the sorted region stays sorted. The manifest now describes 218 tests.

🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift
Validate executable workflow steps, not raw workflow text.
all_workflow_text() concatenates complete YAML files, and the later membership test treats any textual mention of path as proof that the test runs. A path in a comment, trigger filter, disabled step, or metadata field can satisfy the linux-guard check without executing the test. Parse the workflow and inspect executable run commands, including the relevant matrix or condition, before accepting the entry.

…equests `tests/test-execution.toml` requires an entry for every `tests/*.py`, and the preflight validator fails on any unregistered file no matter which pull request is being checked. A test that lands on main without an entry therefore turns every open pull request red until somebody registers it. That happened three times today: #13615's landing left 9 unregistered tests (#13710), then `test_ci_r2_cache_census.py` (#13731), then `test_cmux_settings_jsonc.py` and `test_sync_test_wiring.py` (#13739).

* test: prove the execution registry validator reddens unrelated pull requests `tests/test-execution.toml` requires an entry for every `tests/*.py`, and the preflight validator fails on any unregistered file no matter which pull request is being checked. A test that lands on main without an entry therefore turns every open pull request red until somebody registers it. That happened three times today: #13615's landing left 9 unregistered tests (#13710), then `test_ci_r2_cache_census.py` (#13731), then `test_cmux_settings_jsonc.py` and `test_sync_test_wiring.py` (#13739). This commit adds the regression only, so CI shows it red before the fix. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * ci: fail only the pull request that adds an unregistered test The validator now compares `tests/` against the merge base with the pull request's base commit. A test file with no registry entry is a hard failure only when this branch added it; one that was already unregistered on the base branch becomes a warning, printed as a GitHub annotation and a step summary note, so an unrelated pull request stays green. Everything a branch can only break by editing the registry itself stays a hard failure: entries pointing at missing tests, malformed or duplicated entries, unsupported requirements, manual entries without a reason, and lanes no workflow invokes. The failure now prints the exact TOML block to paste. When a workflow already runs the file directly, the block names `lane = "linux-guard"` and cites the workflow it derived that from; otherwise it lists the live runner lanes. CI never writes the registry itself. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * ci: drop the duplicate test_sync_test_wiring registration #13738 and #13739 each added a `[[test]]` block for `tests/test_sync_test_wiring.py`. The two merged cleanly and left main with the test registered twice, which the registry validator rejects, so every open pull request is currently red on `guards / workflow-guard-tests / preflight`. Both blocks were identical; this removes the second one. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * ci: warn instead of fail on a duplicate registration the base branch already has A duplicate entry was treated as something only the pull request at fault could produce. Today showed otherwise: two pull requests each registering the same test merge cleanly into a duplicate neither one wrote, and it reddens every open pull request exactly like an unregistered test does. The validator now reads the registry at the merge base. A path already duplicated there warns; a duplicate this branch introduces still fails. Parsing moved into `parse_registry(text, label)` so the base revision can be read through `git show` without a file on disk.
